boiler heat loss calculation

WOAH! Is that hot water boiler sized properly? | US

The only way to properly size a hot water boiler is by performing a heat loss calculation. Since the radiation is already installed on a retrofit installation, you do not need to do a room-by-room heat loss, but instead an envelope heat loss. Then, choose a boiler using the DOE output. There are plenty of wrong ways to pick a boiler, like

2 ·This loss occurs from the external surfaces of an operating boiler. For any boiler at operating temperature, the loss is constant. Expressed as a percentage of the boiler's heat output, the loss increases as boiler output is reduced. Hence, operating the boiler at full load lowers the percentage of loss.
